Yes, I have a debug kit with 128mb ram to run them and don't necessarily require them to be original. Would also be interested in other games if they have content that is incomplete or differs from final release of game.
If this is something that simply is not known to exist in the wild (Halo CE beta builds) please feel free to comment.
A few years back I nabbed a unit that used Halo/Blam engine to prototype another game super early in the development cycle, so there's at least some interesting Halo stuff out there. -Doom
Thanks for the replies guys. I kinda figured get my hands on something like a early build might be a bit of a stretch but I would be happy with a debug xbes. Hey I would really love to see what you got is it for sale or available?
